Want the landscaping in your yard to look its best?

Plant health care services are the answer.

For 90 years, General Tree Service has been providing homeowners and businesses in Portland, Salem and Vancouver Washington with tree and landscaping services. Our plant health care services include targeted programs for everything from weed control to insect and disease control.

Our quality service and proven performance have made us THE landscape care company to call in Portland Oregon. Our staff of certified arborists and plant experts, led by Steve Zetterlund, is committed to working with you to create a beautiful and healthy landscape for your continued enjoyment.

Our focus is environmentally friendly programs to get everything in your yard to grow big and strong as that makes them more resistant to disease and pests.

More than 90% of insect and disease problems caused by basic needs not being met

That’s right. If you meet the basic needs of your plants so they are strong and healthy, their own defense system wards off the majority of pests they encounter along with increasing their ability to fight off diseases. This means you greatly reduce the need for pest control.

“An ounce of prevention is worth a pound of cure” is really true when it comes to your plants. So, the question you should be asking is “How can I maintain healthy strong plants?” and the answer is Plant Health Care Services.

Plant Health Care Starts with Ornamental Insect and Disease Control

Our mild climate is wonderful for growing many varieties of trees and shrubs but that also means it encourages disease growth. At General Tree Service, we believe in using an integrated approach to strengthen a plant’s health to protect it against disease and infestation from insects.

Our year-round programs offer inspections to catch any issues early on as that’s when treatments are most successful. Unfortunately, there is no one treatment cure which means repeated treatments are needed to keep the symptoms in check.

We have programs and treatments to control the most common problems found in ornamental landscapes in the Salem, Portland and Vancouver areas.

Dormant application is a valuable treatment

Performed during winter months, our dormant application is one of the most beneficial treatments that can be done to protect the plants in your landscaping. Why? It reduces the number of over-wintering insects and their eggs that will hatch next spring while helping to control bacterial disease infections.

It doesn’t eliminate the need for insect and disease control treatments during next year’s growing season but is a vital component of our year-round Plant Health Care program.

More effective spray treatments

Disease problems can get out of control fast. That’s why General Tree Service is constantly looking for ways to improve service while dealing with our rainy weather. Research has shown diseases are more active during a rainy period and the best results are achieved when disease control products are applied immediately before or after a rain shower.

We have developed a treatment program (assisted by recommendations from OSU) that includes the use of products that make our spray treatments rain fast, rendering them more effective. So, don’t be alarmed if you see us treating your landscape on a showery day. Rest assured, we only spray when the weather is suitable.

Lawn Care Programs

Using our knowledge and experience, we have developed a series of treatments to bring out the highest potential of your lawn.

Our special blend of premium fertilizer is designed to keep your lawn a deep green color without a huge flush of growth.

Free Service Calls

Service calls are free to customers who subscribe to complete programs. We encourage our customers to call if they have questions or need advice about their landscape.

Careful inspection by plant experts

We inspect your landscape before we treat your plants.

Our technicians are trained to recognize insect, disease and cultural problems and will treat affected plants only when needed.

This results in a healthier landscape and benefits our environment by limiting the amount of chemical control materials applied.

I have greatly appreciated the concern and proactive service that General Tree has demonstrated.
They certainly are as motivated to care for my grounds as I am.

Ornamental Bed Weed Control

This program controls weeds year-round in your ornamental beds, bark dust and gravel landscape areas by applying pre-emergents and post emergents as needed.

We'll inspect your landscape on a regular schedule and treat any weeds we find.

Fertilization for Healthier Plants

Plants in urban landscaping don’t receive the benefit of natural fertilization and require additional fertilization to maintain their health and appearance.

Our nutrient blend replaces and supplements the elements used by plants.

Pressure injected, deep root fertilization aerates the soils while placing water and nutrients right at the roots for optimum uptake by the plants. For certain shallow rooted plants, a liquid application may also be applied.

Environmentally friendly programs

General Tree has been using environmentally friendly methods as part of our tree and shrub care programs long before they became so popular.

From the beginning, we have been committed to using the most environmentally responsible products available and registered by the EPA (Environmental Protection Agency).

Our programs incorporate organic or bio-rational products such as summer spray oil, BT and Pyrethrums as a major source of insect control in our Plant Health Care programs. When we are charged with the health of your outdoor environment, we take it very seriously.
